Coal oil is made by heating cannel coal with a controlled amount of oxygen, a process called pyrolysis. Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in largescale industrial processes. The coal is coked, a process ...

The effects of different physical parameters such as pulp density, aeration conditions, and impeller speed on the performance of coaloil assisted gold flotation were investigated in this study. The experiments were conducted using samples taken from an epithermal gold ore deposit. The results demonstrated that increasing the solid concentration in feed pulp slightly improves recovery of gold ...

The Coal Gold Agglomeration (CGA) process was developed some years ago and has the advantage in that gold is recovered by a procedure which has little or no negative impact on the environment. A gold ore containing liberated gold particles is contacted with coaloil agglomerates, whereby the gold is recovered into the coal/oil phase.
